Any grit, sand, soil, glass or metal that enters the digester is removed automatically. This enables the digester to consistently run at maximum capacity, without the need for a periodic shut down to remove grit.

This enables the Fre-energy digester to process shock loads of high strength feedstocks containing fats and sugars that are prone to causing acid indigestion. Removing the foam allows the bacteria to recover quickly to optimum gas production.

At Fre-energy we build our own 80kW CHP's which are self contained on a skid unit. Up to three engines can be installed in a 20ft acoustic shipping container, and any CHP can be replaced with a service exchange unit in a matter of hours.

Our technical team can monitor all information from the control unit and CHP online. They can ensure that the system is achieving optimum performance and alert the client or a Fre-energy engineer of any potential problems.

We use standard agricultural tanks either made from glass enamel steel plates or precast concrete panels, these are quick and easy to erect and are significantly cheaper than poured in-situ or stainless steel.
